Description

Technical Field

[0001] This utility model relates to the technical field of gates, and more particularly to a folding gate. Background Technology

[0002] Railway construction typically follows strict road planning. However, in some areas, train tracks are located within cities and surrounded by towns. The railway passes through roads used by pedestrians, so barriers are usually installed on both sides of the railway to handle the passage of trains. These barriers are usually in the open position and are generally rotated 90 degrees vertically upwards. Due to the long length of the barrier, in windy conditions, the barrier will sway and resonate back and forth. The barrier will experience metal fatigue due to the back-and-forth swinging, eventually leading to bending or breakage of the barrier and affecting its service life. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a folding gate to solve the problem that gate arms are easily bent by wind when parked vertically.

[0004] Based on the technical problems existing in the background art, this utility model proposes a folding gate, including a first rod and a second rod whose ends are hinged to each other by a hinge assembly. The end of the first rod away from the second rod is connected to an organic body. A reversing mechanism is provided in the middle of the first rod. The upper surface of the middle of the second rod is connected to a first wire. After passing through the reversing mechanism, the first wire is located below the first rod and connected to a first wire take-up mechanism. The lower surface of the middle of the second rod is connected to a second wire. After passing through the reversing mechanism, the second wire is located above the first rod and connected to the first wire take-up mechanism.

[0005] Preferably, the first rod has a longitudinal through hole in the middle, the reversing mechanism includes a reinforcing sleeve and a rotating wheel, the reinforcing sleeve has an opening in the middle, the opening of the reinforcing sleeve matches the through hole, and multiple rotating wheels are installed to rotate at the four corners of the reinforcing sleeve. The first and second rods both turn through the rotating wheel and pass through the through hole.

[0006] Preferably, the second rod is fitted with a fixing member, and the ends of the first and second rods are connected to the fixing member.

[0007] Preferably, the end of the first rod away from the second rod is rotatably connected to the machine body.

[0008] Preferably, two sets of limiting mechanisms are rotatably installed inside the machine body. The limiting mechanisms are located below the connection between the first rod and the machine body, and on both sides of the connection between the first rod and the machine body. The first wire and the second wire pass through the two limiting mechanisms respectively, and the first wire and the second wire do not cross inside the machine body.

[0009] Preferably, each set of limiting mechanisms includes two limiting wheels, and the middle of each limiting wheel is provided with an annular groove along the contour. The two limiting wheels contact each other and the annular grooves of both wheels wrap around the first or second line body.

[0010] Preferably, both the first take-up mechanism and the second take-up mechanism are located below the limiting mechanism.

[0011] Preferably, tension springs are hinged to both sides of the first rod and the machine body.

Detailed Implementation

[0017] Example

[0018] Please refer to Figures 1-2This utility model proposes a folding gate, comprising a first rod 1 and a second rod 2, whose ends are hinged together by a hinge assembly 3. The end of the first rod 1 furthest from the second rod 2 is connected to a body 4. A reversing mechanism 5 is provided in the middle of the first rod 1. A first wire 6 is connected to the upper surface of the middle of the second rod 2. After passing through the reversing mechanism 5, the first wire 6 is located below the first rod 1 and connected to a first take-up mechanism 8. A second wire 7 is connected to the lower surface of the middle of the second rod 2. After passing through the reversing mechanism 5, the second wire 7 is located above the first rod 1 and connected to a second take-up mechanism 9. In this design, when the gate needs to be opened... The first wire 6 pulls the second rod 2, which flips and folds downward relative to the first rod 1. Since the first wire 6 is reversed by the reversing mechanism 5, the first wire 6 pulls the first rod 1 to flip and fold 180 degrees. During this process, the second wire 7 can slowly relax the tension as the first wire 6 is pulled. Furthermore, when the gate needs to be closed, the first wire 6 is in a slowly relaxed state, and the second wire 7 will tighten. The second wire 7 will pull the first rod 1 to flip 180 degrees. During the flipping process, the second wire 7 will pull the second rod 2 to flip relative to the first rod 1 and form the longest straight line.

[0019] In specific implementation, refer to Figure 1 , Figure 2 The first rod 1 has a longitudinal through hole 11 in the middle. The reversing mechanism 5 includes a reinforcing sleeve 51 and a rotating wheel 52. The reinforcing sleeve 51 has an opening 511 in the middle, which matches the through hole 11. Multiple rotating wheels 52 are installed at the four corners of the reinforcing sleeve 51. The first wire 6 and the second wire 7 are both turned by the rotating wheel 52 and pass through the through hole 11. In this scheme, the first wire 6 and the second wire 7 are both reversed by the rotating wheel 52. The rotating wheel 52 can reduce friction for the winding and unwinding of the wire and facilitate the transfer of tension. The reinforcing sleeve 51 can strengthen the rigidity around the through hole 11 of the first rod 1 and avoid the risk of the first rod 1 breaking.

[0020] In specific implementation, refer to Figure 1 , Figure 2 The second rod 2 is fitted with a fixing member 21, and the ends of the first wire 6 and the second wire 7 are connected to the fixing member 21. In this scheme, the fixing member 21 is installed on the second rod 2, and the fixing member 21 is used to connect the wire ends of the first wire 6 and the second wire 7. The first wire 6 and the second wire 7 can also be directly connected to the middle of the second rod 2, so that both the first wire 6 and the second wire 7 can exert tension on the second rod 2.

[0021] In specific implementation, refer to Figure 1 , Figure 2The end of the first rod 1 away from the second rod 2 is rotatably connected to the body 4; in this scheme, the first rod 1 can rotate relative to the body 4, and its rotation angle is in the range of 0 degrees to 180 degrees.

[0022] In specific implementation, refer to Figure 1 , Figure 2 Two sets of limiting mechanisms 10 are rotatably installed inside the body 4. The limiting mechanisms 10 are located below the connection between the first rod 1 and the body 4, and on both sides of the connection between the first rod 1 and the body 4. The first wire 6 and the second wire 7 pass through the two limiting mechanisms 10 respectively, and the first wire 6 and the second wire 7 do not cross inside the body 4. In this solution, the limiting mechanism 10 can provide a support point for the first wire 6 or the second wire 7 inside the body 4. When the first wire 6 or the second wire 7 is tightened, the range of the wire between the first rod 1 and the take-up mechanism can be reduced, thereby reducing the area occupied by the wire.

[0023] In specific implementation, refer to Figure 1 , Figure 2 Each set of limiting mechanisms 10 includes two limiting wheels 101. The middle of each limiting wheel 101 is provided with an annular groove 102 along the contour. The two limiting wheels 101 contact each other and the annular grooves 102 of both wheels wrap around the first line 6 or the second line 7. In this solution, the limiting wheel 101 can provide a steering effect for the first line 6 or the second line 7, while reducing friction with the first line 6 or the second line 7, and can limit the movement of the line, reducing the risk of the line detaching.

[0024] In specific implementation, refer to Figure 1 , Figure 2 Both the first take-up mechanism 8 and the second take-up mechanism 9 are located below the limiting mechanism 10.

[0025] In specific implementation, refer to Figure 1 , Figure 2 Tension springs 12 are hinged to both sides of the first rod 1 and the body 4. The hinge point between the tension springs 12 and the first rod 1 is located on the side of the reversing mechanism 5 away from the second rod 2. The hinge point between the tension springs 12 and the body 4 is located directly below the hinge point between the first rod 1 and the body 4. The tension springs 12 can provide a stable tension effect for the first rod 1. They can work with the first line 6 or the second line 7 to improve the stability of the rod. When the first rod 1 rotates 90 degrees, the tension springs 12 can switch the tension to maintain the stability of the first rod 1.

[0026] In a further embodiment, a slot with an upward opening needs to be opened on the top of the body 4. This may cause damage to the internal equipment in rainy weather. Therefore, the connection between the body 4 and the first rod 1 can be achieved by a rotating shaft connection. The connection point between the first rod 1 and the rotating shaft is set on the outside of the body 4. The rotating shaft located inside the body 4 is provided with a third rod connected to the first rod 1. The third rod is used to connect the tension spring 12 and can replace the position where the first rod 1 connects to the tension spring 12. The winding and unwinding of the first line 6 and the second line 7 can be changed and operated by the wheel.

[0027] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
